Notes:
A continuous miner is one of wall mechanized coal face; its design quality andperformance have directly effect on coal productivity and economic benefits. A pick on acontinuous miner, contacting with coal and rock, is a tool cutting directly coal and rock, its forcecondition during it cuts determines directly loads of the cutting mechanism, pick wear and tear,fabric vibration and cutting performance of the machine, is the basis for the design of a continuousminer. By considering a variety of factors, a mathematical model, including the coal and rockproperties, structural parameters of a pick, pick sequence, cutting parameters of the continuousminer, is established in the paper, visualization software which can be directly reflected pick' forceson the continuous miner is design. On this basis, pick' forces of a continuous miner under differentworking conditions are simulated and studied, which create conditions for understanding pick' forceduring cutting process of a continuous miner, computer-aided design of the cutting mechanism,dynamic design and research of the machine
